Dynamics of Built-Up Areas over The Past 30 Years According to Remote Sensing Data in the City of Valdivia, Chile
(IEEE, 2018)
The dynamics of built-up areas over the last 30 years in the city of Valdivia was analyzed according to Landsat satellite imagery data. For ETM+/Landsat-7 and OLI/Landsat-8 instrumentation systems, method of automatic ...
Inverse Modeling of GPS Multipath for Snow Depth Estimation-Part II: Application and Validation
(Ieee-inst Electrical Electronics Engineers Inc, 2014-10-01)
GPS multipath reflectometry (GPS-MR) is a technique that uses geodetic quality GPS receivers to estimate snow depth. The accuracy and precision of GPS-MR retrievals are evaluated at three different sites: grasslands, alpine, ...
New data on the geodynamics of southern Peru from computerized analysis of SPOT and SAR ERS-1 images
(Elsevier, 1996)
Several geological structures are extracted from SPOT-Panchromatic and ERS-1 radar images of the Central Andes (Arequipa area, Southern Peru). Our new methodology of numerical image processing is an aid for identification ...
